andhas for its object the provision of im-fl proved devices for connecting, se aratcd shafts and for obtaining a'universa movement between the two.

Another object of the invention is the provision of antifriction-balls or rollers located between separable plates which connect the forks of two shafts, and whereby friction is reduced .and ease of movement attained, as will be hereinafter set forth. v

Other objects of the. invention will be stated in the following detailed description.

In the accompanying drawings, Figure 1 is aside-elevation artially in section'of the imv proved universalcoupling or joint. Fig. 2 is an edge view in elevation, showing insection va twoart dust or dirt excludin casinir .D

which may be employed to protect the parts. Fig. Sis a sectional view taken on line of Fig. 1. Fig. 4 is a transverse sectional view. And Fig. 5 is a sectional view taken on line 5 5 of Fig. 1 looking in the direction of the arrow.

Like numerals designate similar parts throughout the several views.

'Referring to the drawings, the numeral 1 indicates a shaft to which is secured, or made integral therewith, a fork 2,-said shaft having I 'a collar 3 upon which the hub 4 of one section of a dust or dirt-excluding casing, designated in a general way by 5, is mounted. Opposite the shaft 1, or located at an angle thereto, may be required, is a shaft 6 having a collar 7 upon which the other section 8 of said casing .5 is secured in the same manner. This shaft also provided With a fork 9, as will be herc by bolts and nuts 12 which serves as a reservoir for lubricant conducted therefromA l through openings 102. To reduce the Weight of plates 1() and 11 stock is removed as at 103 (see-.Fig..4). In the ends of the arms of each fork 2 and 9 are o positely-disposed, curved recesses 13, 13 or the reception of balls 14, 144 and in the plates 10-11 are sockets 15-15 for the reception of said balls, so that when the parts are united a comparatively frictionless rocking movement is assured.

Preferably the hubs of the forks-aresecured to the shafts by pins 16-16, although as stated said forks maybe made integral with the shafts without departurefrom the invention. f

In assembling the parts of the improved joint the balls are put in place, and the plates are united by means of the bolts 12, as illustrated in Figs. and 5, after which the shafts may be inclined toward each other, or one section'may he moved with relationto the other in the ordinary manner of universal joints with ease and without injurious wear, all foreign matter being excluded from 'the joint by the sectional casing described.

As will he obvious the ball-sockets inthe forks and plates may be hardened if desired, or may be composed 'ol inserted steel plates.

Changes may be made in the various details of the construction without departure from the invention, which is not limited to the exact details described.

Having thus described my invention,"

what I claim is- 1. A universal coupling comprising a pair of shafts, each having a fork providedfwith ball-recesses 1n its arms, plates in which said forks are inserted, cach plate having ball-reclasses, balls and moans for uniting said 5f. The combination, with a pair of forked y shafts, cach fork having ball-recesses 1n its arms, of plates slotted to receive the arms of the forks means for uniting said plates; and balls located in the recesses of the arms and plates.
